A power tool assembly includes a hand-held power tool, a dust collector removably coupled to the power tool, and first and second power tool battery packs each of which is interchangeably coupled with the power tool and the dust collector for separately powering the power tool and the dust collector, respectively.

Provided is a tool that includes a handle assembly including a top portion and a bottom portion. The tool also includes a lock plate disposed between the top and bottom portions and having a deflectable arm having a free end biased towards the top portion, a fixed end opposite the free end, an inner edge, an outer edge, and a detent near the free end and the inner edge. The tool additionally includes a blade having first and second ends, an indent in a bottom surface of the blade near the first end for engaging the detent in a closed position, and a ramp on the bottom surface near the indent defining a reduced thickness portion of the blade that reduces in thickness from the indent towards an edge of the blade to reduce contact between the detent and the blade during rotation of the blade.

A toothbrush with a push-back replaceable brush head includes a handle portion, a handle front section moveable inserted into the handle portion and having a supporting platform, a push mechanism including a push plate and a locking plate stacked together and penetrating through the handle front section, the push plate and the locking plate secured onto the handle portion; a brush head replaceably installed on the supporting platform, another end of the locking plate locked onto the brush head and the handle front section; wherein the handle front section is pushed toward the handle portion to allow the locking plate, the handle front section and the brush head to release from locking while the push plate pushes the brush head away from the supporting platform. Therefore, the release of locking and disengagement of the brush head can be achieved at the same time to facilitate operations of the toothbrush.

An offset connector subdivides a long, slender tool or implement handle. The offset connector may be provided with one or more unitary or replaceable grips. The additional grips serve as secondary or tertiary hand holds that enable more adaptable and capable ergonomic manipulation of the tool or implement. The offset connector is inserted intermediate between a primary handle grip and the tool or implement head, thereby subdividing the long slender tool or implement handle into at least two separate handle segments. Each handle segment is inserted into a handle segment receiver socket, and is affixed therein using a bolt, screw, or other fastener that is longitudinally co-axial with the longitudinal axis of the handle segment. Some embodiments establish fixed spacing between the primary handle, secondary handle, and implement. Other embodiments provide variable spacing therebetween.

A multipurpose utility attachment device for equipping a variety of tools to an adjustable shaft includes a grip. The grip is a handle and has a flat end. A telescopic shaft comprises a first portion, a second portion, and a pair of spring pins. A proximal end of the first portion is coupled to the flat end of the grip. The second portion is nested within the first portion. The second portion can adjust the length of the telescopic shaft by moving within the first portion. A pair of spring pins is positioned within the second portion and secures the second portion in a fixed length relative to the first portion. A second spring pin is used for securing a utility attachment to the telescopic shaft. The utility attachment can be a variety of wilderness survival tools. A hammock attachment can be used by a pair of telescopic shafts.
